Eleventh Grade Science Projects (157 results)

Science Buddies' eleventh grade science projects are the perfect way for eleventh grade students to have fun exploring science, technology, engineering, and math (STEM). Our eleventh grade projects are written and tested by scientists and are specifically created for use by students in the eleventh grade. Students can choose to follow the science experiment as written or put their own spin on the project.

For a personalized list of science projects, eleventh graders can use the Science Buddies Topic Selection Wizard. The wizard asks students to respond to a series of simple statements and then uses their answers to recommend age-appropriate projects that fit their interests.

Science Fair Project Idea
Scientists recently found that some small drugs can stop infection by the deadly Ebola virus in its tracks. Lab researchers found that these drugs bind to a protein that the Ebola virus uses to enter our cells, and this is how infection is prevented. However, this also means that the bound protein no longer functions in our cells. How might these drugs accidentally disrupt important biological processes in our bodies? What other proteins might these drugs bind to? In this science project,… Read more

Science Fair Project Idea
We encounter an amazing array of colors every day, from the greens of plants and the many colors of their flowers, to the pinkish blue of a sunset, to the artificial coloring in beverages. How do we perceive all of these colors? When light hits an object, some of that light is absorbed by the object, and the light that is not absorbed is what we see. In this science project, you will build a simple spectrophotometer from a cell phone and use it to investigate how visible light is absorbed by… Read more

Everyone knows electricity can create heat, especially because our electrical appliances tend to warm up when turned on. But wouldn't it be cool to do the reverse — generate electricity from heat? In this science project, you will study why it happens, measure the effect, and then use the phenomenon to build your own device, a thermocouple thermometer, that will enable you to convert heat into electrical energy.

Do you wake up at the crack of dawn, or do you need an alarm clock to wake you up each morning? It may surprise you that the two are not always in synch. Nowadays, we use Standard Time to set our watches instead of Solar Time. Which method of timekeeping is the most accurate? Get ready to synchronize your watches! Timekeeping is the science of how to keep time with precision and accuracy. People have been finding ways of measuring time for thousands of years, usually based on the movements… Read more

Can you imagine Valentine's Day or Halloween without chocolate? Well, if you're a chocolate lover brace yourself for the bad news. According to the United States Department of Agriculture (USDA), "Worldwide demand for cacao now exceeds production." If there isn't enough cacao, the major raw ingredient for chocolate, then the chocolate supply will dwindle. Hang on! Before you start rushing to the store to buy all the chocolate you can get your hands on, a solution is already in the works. In… Read more

Science Fair Project Idea
Most people are not aware that the soil around them is a battle scene. The combatants are very small—bacteria on one side and bacteriophage on the other. The bacteriophage (or phage for short) try to pierce the outer coats of the bacteria and inject them with phage DNA. If successful, the DNA will take over the inner machinery of the bacterial cells and force them to make many copies of the phage. After the copies are made, the bacterial cells break apart, releasing new phage that start… Read more

Safety Notes about Neodymium Magnets: Handle magnets carefully. Neodymium magnets (used in this science project) are strongly attracted and snap together quickly. Keep fingers and other body parts clear to avoid getting severely pinched. Keep magnets away from electronics. The strong magnetic fields of neodymium magnets can erase magnetic media like credit cards, magnetic I.D. cards, and video tapes. It can also damage electronics like TVs, VCRs, computer… Read more

How many websites do you have accounts with that store personal information like your name, email, phone number, or mailing address? If the people running these websites are not careful, hackers could gain unauthorized access to, and even change or delete, your information. They can do this using something called SQL injection, which involves entering malicious code into text fields on a website. In this project you will learn how SQL injection works and figure out how to prevent it. Read more

Science Fair Project Idea
Can bacteria be altered to produce life-saving insulin for diabetics? Or change color to indicate the presence of a harmful toxin? Yes, it can! Using biotechnology, scientists work daily on problems like these. It starts with selecting a gene you want bacteria to produce and creating a sequence of DNA that has that gene and a promoter that will help express it at the right time and at the right levels. The next hurdle is actually getting this engineered DNA into the bacteria and… Read more

Science Fair Project Idea
This is a great project for someone interested in both stargazing and photography. Bright city lights and even the light of the full Moon obscure the dimmest stars, which can make identifying constellations more difficult. In this astronomy science project, you will calibrate a digital camera to measure the skyglow in different locations. This can be a great tool to comparing the quality of different star viewing locations. Read more
